Solution

The correct option is C Segregation

Mendel in his monohybrid cross experiment, self-crossed the F₁ hybrids(Tt), F₂ generation is raised. In the F₂ generation, 3 tall plants and 1 dwarf plant phenotypically or 1(TT) 2(Tt) 1(tt) genotypically are formed. He stated that each factor in a pair separate during gamete formation so that each gamete receives only one factor for each character. It is called Law of Segregation or purity of gametes. It occurs during the process of meiosis.
So the correct option is ‘Segregation’.
